Well, if you're going to give props for a line, then give them where they are due: Homer. To quote the man himself (as said to Bart):

I want to share something with you:
The three little sentences that will get you through life.
Number 1: (whispers) Cover for me.
Number 2: Oh, good idea, Boss!
Number 3: It was like that when I got here.

That's where the credit goes for that quote. Pulled from One Fish, Two Fish, Blowfish, Blue Fish at the SNPP."Oooo, he card, read good!"
